HD video sequences are widely used in today's multimedia systems and many of these are encoded with H.264 codec. However, it is still challenging to develop a high-performance H.264 encoder because the H.264 encoding process needs a large amount of computations and memory accesses. In this paper, a novel H.264 encoder is described. This encoder can encode video sequences of full HD 60i at double speed...
In this paper, broadband planar antenna with a trimmed elliptical element and a ground conductor with two slits is proposed, in order to improve more a radiation pattern. The trimmed elliptical element and the ground conductor are printed on dielectric substrate, and the two slits in the ground conductor are set to both sides of a feeding point. The characteristics such as return loss and radiation...
The experimental results on the exciton transfer obtained in pyrene microcrystallites are discussed with the help of a one-dimensional theory. The excitation spectrum for luminescence observed in pyrene microcrystallites consists of a sharp line and an exponential tail. Such a band shape is obtained theoretically for a one-dimensional model using the tight-binding approach. The exciton bandwidth is...
